BodyFit and The 3% Bodyfat Solution, Good News and Bad News.
The 3% bodyfat reading is the absolute minimum reading and that is the number I keep getting with the new Withings BodyFit regardless of Athlete mode being on/off. So, I went and also took an Inbody analysis in a local pharmacy (also electrode handles) and guess what, it shows 3% Body fat as well.
This made me think that this technology/algorithm in those machines are not designed for a body type of mine:
Lean Body
Height: 175 cm
Weight: 69 kg
Body Fat: 8-10% (Can't confirm yet since all those devices are not giving a reading)
The Solution (Probably):
Reducing my height in my profile artificially (from 175cm to 170, 165, 160cm, etc) finally results in increasing the body fat % per attempt, so it is not hard locked, it is indeed an algorithm issue.
Actual Height: 175 cm = 3% BF
Fake Height: 170 cm = 3.4% BF
Fake Height: 165 cm = 4.1% BF
Fake Height: 160 cm = 5.5% BF
What I am going to do is to take a DEXA scan for the first time in two weeks, confirm my body fat and then do the following:
- Assuming the DEXA scan shows 9% BF.
- Set Withings profile artificial height to a number that will result in giving the 9% BF.
- And that will be my new baseline.
The drawback that other metrics that depend on height will be inaccurate but for my goals Weight + Body fat + Muscle Mass is the reason I got this scale.
I hope Withings staff read this and start looking into it and maybe can come up with a real solution.
Because honestly, I have never ever felt that I wasted money on anything close to this. My old cheap feet-only scale giving an inflated BF but actually moves and can be used as a trend is literally more useful at this point than this premium scale.
